New Varieties to be added to the Bordeaux Melting Pot to combat global warming

IN an attempt to combat the rising heat due to global warming; new varieties approved were approved recently at the syndicate’s annual general meeting Bordeaux and Bordeaux Superior were four reds, Arinarnoa, Touriga Nacional (portuguese), Marselan and Castets, and three whites, Alvarinho (found in Spain and Portugal), Petit Manseng (Jurancon) and Liliorila.

The vines were chosen primarily for their reduced susceptibility (but not resistance) to disease, later harvesting potential and ability to maintain acidity and volume in the face of climate change’s warmer weather and unseasonal frosts. All while maintaining existing flavour, aroma, production and quality levels.

The new grape types in more detail

REDS

Arinarnoa: a Tannat/Cabernet Sauvignon cross that is less susceptible to grey rot damage, with low sugar levels and good acidity. Wines are well-structured, colourful and tannic with complex and persistent aromas.

Touriga Nacional: a late ripening grape that can reduce the risk of frost or heat damage and is less susceptible to most fungal diseases apart from excoriose (dead arm). Wines are complex, aromatic, full-bodied, structured, colourful and suitable for ageing.

Castets: a forgotten Bordeaux grape variety that is less susceptible to grey rot, powdery mildew and mildew. Wines are colourful and suitable for ageing.

Marselan: a late ripening Cabernet Sauvignon/Grenache cross that is at lower risk of spring frost, heat, grey rot, powdery mildew and mite damage. Wines are colourful, distinctive and suitable for ageing.

WHITES

Alvarinho: an aromatic grape that can compensate for flavours lost due to hot weather, at lower risk of grey rot damage, lower sugar levels and good acidity. Wines are aromatic with good acidity.

Petit Manseng: a late ripening, aromatic variety that is at much lower risk of grey rot damage. Wines are soft with sustained aromas.

Liliorila: a Baroque and Chardonnay cross that, like Alvarhino, offers highly aromatic qualities that can be used to compensate for other aromas lost to heat. It is less at risk of grey rot damage. Wines are aromatic wines, powerful and flowery.
